This invention relates to pressing machines, and more particularly to"such machines used in the pressing of various parts I of garments duringthe process of manufac- 61 turing: H i a One of theobjectsof theinvention is to provide a machine of the character referred to, having asteamta' ble' or buck forsupport ing the material to be pressed, apivoted and 101 movable steam heated pressing iron, means for exertingpressure on the said iron against the saidbuck, and means for lockingthe iron in the said position. w I

Another object of the invention is .to profivide means for adjustingthesaid pressures 'durin the pressing operation.

A. urther object of the 1 invention is to" provide means for releasingthe saidpressure locking means.

A still further object of the inventioni is to so mount the pressurelocking means that it maybe swung in and out of operative po- 'sition.-vj Yet another object of'the invention is to eliminate a great deal ofthe hard labor required to press garments or portions thereof,

work instead of strong men as is necessary with the present day machinewhich isknown as the'jumper type, and in the use of which thepressers-jump up and down upon a foot lever to exert the requiredpressure upon the garment pressed. 7

Another object is to produce a device of the character describedin whichthe maximumsimplicity of construction and operation is secured. I r I r1 Other objects and advantages will appear asthe nature of theimprovements is better understood, the invention consistingsubstantially in the novel arrangement and corelation of parts hereinfully described, and illustrated in the accompanying drawings, whereinsimilar referenc'echaracters are used to describe corresponding partsthroughoutthe several views, and then finally pointed out andspecifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventiveconcept suggests .to'be understood from an illustrative, rather adjustedposition. so that girls may be employed to 'dosuch g indicatesa tablesupported on a frame 11; At

A

short pipe 16 is screwed into the said bore 15 and locked in position bymeans of a nut 17. Rotatably secured in the said pipe 16 is one end of apipe line 18 whichat its opposite end is ofi'set and has secured theretoby. means of a clamp 19 oneend of a hose 20 leading I into a pressingiron 21. A secondhose 223 0 leads from the pressing iron 21 to-asimilarly ofiiset pipe line 23 and is secured thereto by Y means of aclamp 24 similar to the clamp 19.

return to the source of supply.

A bracket 33 secured to the bottom of the table and extending to therear thereof,

swung down against the buck or material has pivotally mounted thereon at34 a lever 35, the upper arm 36 of which terminates in upper and lowerbearings 37 and 38.

Between the said bearings there is swingingly supported on a rod 39, abracket 40 having a slideway 41 in'which there is slidably supported aslidebar 42. The said slidebar terminates at the front thereof in a hub43 (see Figs. 1, 2 and 5) having a threaded open ing 44 through whichpasses a threaded stud 45 terminating in a ball 46. I Suspended from thesaid ball is a hub member .47 from the bot tom of which extends a stud48 entering into the pressing iron 21, thus forming a universal jointfor the said iron. Ball bearing rollers 50 and 51 provide easy slidingmeans for the bar 42.

The lower end of the lever '35 terminates in an arm 55 (see Fig. 2)which is engaged by a yoke 56, the said yoke having a rod 57 extending'therefrom and in engagement with a foot lever 58 pivotally mounted at59. The said foot lever 58 is depressible against the tension of a pairof springs 60 the top ends of which are anchored at the forward end ofthe bracket 33 and the bottom ends pass through ears of a slot-ted plate61 adjustably secured to the extreme forward end of the lever armPivotally'mounted at 62 on the foot lever 58 and straddling same is atoothed rack or yoke 63 which is under the tension ofa pair of springs64. When the foot lever 58 is depressed the said rack will be broughtinto engagement with pawl 65 pivoted at 66 onthe lower'portion of theframe 11, a spring 67 tending to maintain the said pawl in desiredposition. T heengagement of the rack and pawl provide locking means forthe foot lever or pressure applying means.

The operation of my improved pressing machine is as follows. The iron 21is first adjusted to about the required height above the buck 12 bymeans of turning thehead of the screw 45. When in the above namedadusted position pin 70 in the slide bar hub 43 will be forced into oneof two slots 71 'in'the screw 45 by means of a spring 72 secured to thesaid hub. After this initial adjustment the foot lever 58 is depressed,the iron 21 being thereon, and the foot lever becomes automaticallylocked by means of the rack 63 and pawl As not all of the materialspressed are of one thickness and require different pressures thisjumping is eliminated, as I may vary the pressure while in the act ofironing or pressing by merely depressing the foot lever 58 further thanthe dot and dash position shown in Fig. 2 so that the pawl will engageon an upper tooth of the rack 63.

To release the pressure applying foot lever, I have provided a second orauxiliary foot lever pivoted at 81 onthemain foot lever 58, andconnected by means of a slotted link 82 to the rack member 63. Bydepressing the said auxiliary foot lever, a roller 83 at the end thereofwill engage a cam surface 84 at the bottom of'the said rack and causesameto swing into the full line position shown in Fig. 4. The lockingrack 63 may be brought into inoperative position by swinging same aboutits pivot 62 and latching same in the dotand dash position (Fig. 4) bymeans of a link 85 pivotally secured at'86 to the main foot lever 58.

23 are connected together by means ofa link 90, this connection andthe-fact that the said pipe lines are rotatably mounted takes all thestrain off the hose 20. and 22 and prevents.

their breaking due to excessiveand constant pull on them during thepressingoperatio'n.

It will also be seen by referring to Fig. 2, that when the pressingironz2l ishpre'ssed down against the buck, the said p-ressurewill of thesaid slideway thus relievingthe roll-' ers 50 and 51 of all strain.

The forward movement of the pressing iron carrying bar may be limited byone of a number of removable stop .pins 93 in the said bar, theparticular stop utilized depend ing upon the length of the buckemployed.

-From the foregoingit will! be seen that I haveprovided a simple, andeasily operable pressing machine in which the pressure applying meansmay be releasably'locked in any desired position and additional pressureadded during the pressing or ironing operation. and thus eliminate agreat deal of time and labor formerly required for performing this typeof work with theexisting machines. Having described my invention what Iclaim as new and desire to secure byLetters Patent is: 1

1. In a pressing machine, a slideway, a bar slidably mounted therein, apressing iron carried bysaid bar, a support having a pair of steamconduits, a pipe line pivotally mounted in. each of the said conduits, alink connecting the said pipe lines, the said link being so located thatthe movement of one pipe line will enforce the movement of the other anda hose between each of the said pipe lines and the pressing iron.

2. In a pressing machine, a movable pressing iron, a support having apair of steam By referring to Figs. 1 and it will be seen 1 that the twohose carryingpipe lines 18 and conduits, a pipe line pivotally mountedin each of the said conduits, rigid connecting means between the said pie lines, so located with respect to the sai pipe lines that the movementof one pipe line will enforce the movement of the other and ahosebetween each of the said pipe lines and the pressing iron. 7

3. In a pressing machine, a movable pressing iron, a support having apair of steam conduits, a pipe line pivotally mounted in each of theconduits, an offset portion on each of the pipe lines, a link connectingthe-said oflset portions to transmit the movement of one pipe to theother, and a hose between each of the said ofiset portions and thepressing. iron.
